The example of cutting corners that Arthur Miller uses in All My Sons may be an extreme one—a greedy manufacturer knowingly selling cracked plane cylinders to the Air Force—but the underlying attitude it displays is all too common in present-day corporate America.
A particularly notorious example comes from the Boeing 737 Max scandal. Boeing, the world's largest aerospace company, knew that there were problems with their 737 Max plane and yet took no action. In fact, they even tried to hide the plane's faults but hid them from the FAA. Instead, they allowed the model to be used in commercial flights, with tragic results.
In October 2018, 189 people were killed in a Lion Air crash. Five months later, a further 157 people were killed when an Ethiopian Airlines flight crashed. In both cases, the plane used was a Boeing 737 Max.
If a large corporation like Boeing can engage in such reckless and irresponsible behavior, one can only imagine how common such corner-cutting measures are when it comes to those further down the corporate food chain. It would seem that there are plenty of Joe Kellers in this world, showing complete disregard for corporate responsibility, whether it's through polluting the environment or scrimping on health and safety for their workers.
In all such cases, the relevant corporate actors are motivated by the same concern as Joe Keller: to make as much money as possible. All too often, this overriding concern with the bottom line means that concerns for the welfare of workers, consumers, and residents affected by environmental pollution, end up going by the board.
